. To all whom it may concern.-

Be it known that I, EMILE LANGJAHR, a citizen of the Republic of France,residing at Triibau, Moravia, in the Empire of Austria- Hungary, haveinvented certain new and useful Improvements in Apparatus forSimultaneously Weaving Two or More Fabrics, (for which I have obtainedthe following patents: in Great Britain, No. 4,108, dated March 2, 1892;in France, No. 219,728, dated February 27, 1892; in Austriallungary,dated March 7, 1892, No. 42 and No. 4,085 ;in Switzerland, No. 830,dated March 28, 1892; in Germany, No. 65,354, dated April 6, 1892, andin Belgium, No. 99,158, dated April 3, 1892,) of which the following isa specification.

This invention relates to apparatus employed in looms for simultaneouslyweaving two or more fabrics, for the purpose of forming false selvages.In such apparatus as at present generally constructed, one of the falseselvage threads passes alternately to the right and to the left of afixed thread, and several attempts have been made to secure by suchapparatus a selvage which is not liable to unravel, but without completesuccess. In place of adopting this method of forming the false selvages,I employ a rotary motion of false selvage threads so as to form withthem a kind of continuous cord in the strands of which the weft threadsare very securely bound.

An apparatus constructed for the purpose of this invention isillustrated by the accompanying drawings to which reference is to behad, in which- Figure 1 is a side elevation. Fig. 2 is a plan. Fig. 3 isa front elevation of the twister for the selvage threads. Fig. 1 is aplan of the same. Fig. 5 is a side View of a twister. Fig. 6 is an axialsection thereof. Figs. 7, S, 9, and 10 illustrate the guides and theirconnected parts. Fig. 11 shows the bar which carries the dogs to actuatethe twisters. Fig. 12 illustrates the fabric.

The apparatus consists of two essential portions; that, is tosay,-first, of a support I) upon which are fixed two pins 0 0 each ofwhich has mounted upon it a metal disk cl having a maximum diameter ofabout four in Germany Apn'l 6,1892,N0.65,354.

inches. These two disks are provided with teeth and are geared together.The support I) may be fixed upon an iron bar a secured to the framing ofthe loom preferably below the warp, and in such a manner that the twodisks (1 are respectively opposite to the selvagcs which are required tobe produced.

Second, the apparatus consists of a vertical guide (1 in the middle ofwhich there is mounted an iron or steel bar r, carrying a double hook s,the shape and dimensions of this hook and of the bar being arranged tosuit the work to be done in each case. The guide 'q is arrangedperpendicularly between the two selvage cords and behind the healds andmails. Each of the disks carries upon its front side, or the side facingthe loom, a bobbin having four threads thereon, and four thread guides,each bobbin turning upon the same pivot as the disk. This pivot ishollow and is traversed by a central thread which passes through thehollow pivot from a bobbin arranged upon the apparatus. The pasthethread tension regulator f". The four thread guides e are equally spacedaround the edge of the disk, and each of them is provided with an eyewhich receives a thread from the bobbin thereon. At the back of eachdisk there are arranged four driving studs 2', equally spaced andarranged in a square, and with these there engage suitable clicks ordogs K by means of which the disks may be turned at each stroke of thelay through either a half or a quarter turn as may be desired. A detentZ, is arranged to press by means of a spring 0 against two of thedriving studs 1', so as to keep the disks in afixed position after eachhalf or quarter turn. A flat bar j which carries the clicks or dogs Kreceives through the intermediary of a suitable cord, or wire 25, or ofother suitable connecting device, from the lay, a to and fro mo tion ofsuch a kind that the clicks when they studs of the disks (1, impart tothem a half turn for each stroke of the lay, and a quarter turn onlywhen a single click only operates upon the driving studs, one clickoperating upon the movement of the bar j in one sage of this thread isregulated and guided by are both arranged to act upon the driving 5 theaction of a spring acattached to the other end of the flat bar.

If it should be desired that the disks (1 be turned through a half turnfor each stroke of the lay, the two clicks will remain down and inoperation,but if on the contrary,aquarter turn only should bedesired,one of the clicks will be put out of action by lifting it out ofengagement against the flat barj, by means of a disengaging screw orotherwise as indicated by Fig. 11. Further, the two clicks K areconnected by means of cords k with the stop motion K of the loom bymeans of a screw eye on each click, and a bell-crank lever or otherequivalent device. By this means the operative is in complete command ofthe apparatus for the purpose of piecing broken ends and for otherpurposes, for, independently of this automatic disconnecting of theclicks, she can also put them out of action by hand.

The two disks which carry the bobbins, because of the engagement oftheir teeth, turn one to the right and the other to the left, and theholes to bored and tapped in the flat bar j permit the positions of theclicks to be altered if necessary.

The reciprocating bar 0" which carries the double hook s is carried intwo grooves or slides formed in the middle of the guide q, and is movedpositively in one direction at the same time with the healds at eachstroke of the lay. The return movement is effected by a light spring 4",or by a weight.

The threads for the false selvages pass from the bobbins f through theirrespective thread guides, and a long slit z in the guide q, the fourthreads of the right bobbin to the right of the double hook the fourthreads of the left bobbin to the left, and thence directly through thedents of the reed. The long slit z in the guide is larger at the one endthan at the other as shown in Fig. 8, and forms a kind of chamber ch, oneach side of the hook. It is in this space or chamber that the bobbinthreads successively present themselves to the hook.

During the operation of the loom, the two disks 61 turn one quarter orone half turn for each stroke of the beat up, and twist the threads fromeach bobbin into a cord. At each stroke, the double hook seizes, to theright and to the left, a thread from each bobbin, and these threads arethen moved with the healds so that the shuttle may pass. The threads arethen returned simultaneously with the shed, and at the next stroke thefollowing two threads are presented and moved, always one to the rightand one to the left of the double hook, and these motions are repeatedthroughout the weaving so that for every stroke the positions of thethreads are changed in the chambers, by being turned around each otheras they approach and leave the hooks.

The false selvages obtained as hereinbefore described arecompletelysolid, and greater or less substance may begiven to them byusing thicker or thinner harder or softer yarn as may be required by thefabric to be woven.

The tension of the false selvage threads may be regulated by means ofindia rubber cords secured to screws g secured in the disks. These cordspass over the bobbins on which they act as brakes, and the amount offriction may be regulated at will by turning the screws.

By employing on one bobbin threads of different, colors, a multi-coloredtwist edging may be obtained, such as cannot be secured by any othermeans and which may thus form a characteristic meansfor identificationor trade mark.

Several of the disks and related parts may be arranged on the same barso as to enable more than two fabrics to be woven simultaneously and byemploying smaller disks and by super-imposing two or more ranges ofthem, the narrowest ribbons may be woven.

More or fewer than four threads may if desired be used on each bobbin asmay be required in particular cases, butfor ordinary purposesI prefer toemploy four as described.

While I have shown the twisting apparatus as placed below the warp andthe hooks arranged to lift the threads, yet I do not limit myself tothis precise construction since the relative positions of the parts, andtheir direction of movement may be considerably altered withoutdeparting from the spirit of my invention.

When the apparatus is arranged below the warp, it is preferred to coverit with wire work grill or grating to prevent the entanglement orbreaking which might possibly arise from contact of the warp threadswith the false selvage threads.

Having now particularly described and as certained the nature of my saidinvention and in what manner the same is to be performed, I declare thatwhat I claim is- 1. In an apparatus for producing false selvages, thecombination with two bobbins each carrying two or more threads, ofarotary disk concentric with each bobbin and having a guide for eachthread, means for driving said disks intermittingly, and means forlifting said threads in succession, substantially as described.
